Abstract | A new method of ridding light fractions of South Uzbek oils of sulfur compounds is described. It is shown that upon oxidation of the sulfur compounds not only their solubility changes, but also their boiling point rises markedly. The boiling points of the oxidized sulfur compounds and the respective hydrocarbons differ by several scores of degrees. This allows separation of oxidized sulfur compounds by fractional distillation. Fractional distillation makes the purification process much simpler compared to the extraction method and reduces energy consumption substantially. |
